Greenhouse warming researcher James Hansen stated in a recent paper that using nuclear energy to create electricity instead of dirty coal power plants has prevented 1.84 million deaths from the result of air pollution.

If he can specifically endorse development of MSR that would be even better.

R&D on advanced technologies, including thorium reactors with the potential to ameliorate remaining concerns about nuclear power, was stifled, seemingly because it was too promising. Powerful anti-nuclear forces had their way with the Democratic Party. “Green” organizations had indoctrinated themselves in anti-nuclear fervor, and their intransigence blinded them to the fact that they were nearly eliminating the one option for abundant clean electricity with inexhaustible fuel and a small planetary footprint.

The world needs energy. We've got to develop a new generation of nuclear-power plants, which use thorium-fueled molten salt reactors [an alternative nuclear technology] that fundamentally cannot have a meltdown. These types of reactors also reduce nuclear waste to a very small fraction of what it is now. If we don't think about nuclear power, then we will leave a more dangerous world for young people.
